SPECIFICATION forming part of Letters Patent No. 308,167, dated 'November 18, 1884.

Application tiled January 3, 1884. (No model.)

To all whom, t may concern.-

Be it known that I, GILMAN JAQUITH, of Maysville, in the county of Mason and State of Kentucky, have invented certain new and useful Improvements in Spindle-Bolsters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to bolsters for spindles such as are used in cotton-spinning inachines; and it has for its object to provide a device which shall possess superior advantages in point of simplicity, durability, and general efciency, as will be hereinafter fully described, and particularly pointed out in the claim.

In the annexed drawings, Figure lis a vertical sectional view of my improved spindlebolster. Fig. 2 isa view of one side of the same; Fig. 3 is an end view of the bolster. Fig. 4E is a vertical sectional view of the spindle-bolster with its surrounding bolster-case. Fig. 5 is a perspective view ofthe bolster.v

The same letters of reference refer to the same parts in all of the figures.

A inthe drawings is the bolster, which is preferably constructed of iron, and which consists of the central cylindrical portion or waist,

B, provided at or near the upper end with aV tapering annular head, C, and having at its lower end an annular enlargement, D.

E designates the cylindrical bolster-case, in which the bolster is inserted. Said bolstercase is enlarged at its upper end to provide the oil-cup E', forming a receptacle into which lubricating material may be poured. The bolster-caseis of such diameterinteriorly that the annular enlargement D at the lower end of the bolster shall t loosely within the same, while the tapering annular head C at the upper end of the bolster fits snugly in the bore of the bolster-case at its upper end, whereby the bolster is suspended and held from rotation. The tapering annular head G and annular enlargement D of the bolster A are provided with longitudinal grooves or passages F, through which the oil may pass from the oil-cup E into the reservoir or chamber G, be- 5o tween the bolster and bolster-case. The waist of the bolster is provided on opposite sides with longitudinal slots I-I, alternating as shown, through which the lubricant is admitted to the spindle, which has its side bearing in said bolster, and which, being freely lubricated, will rotate freely without tremble or jar.

By reason of the tapering annular heads at the upper end of the bolster it is unnecessary to employ a set-screw or other fastening de- 6o vice for securing the bolster in its case, and the bolster is self-centering. The annular enlargement D at the lower end of the bolster being of less diameter than the bore of the bolster-case admits of a certain degree of lateral motion of the bolster within the bolster-case, which enables the spindle to find a vertical center of rotation, especially inasmuch as a cushion of oil vis formed between the annular enlargement D of the bolster and the surroundo ing wall of the bolster-case.

One of the important advantages `of my invention is the omission of projecting screwheads on the outer side of the bolster-case and openings which allow oil to leak out. Such projections catch lint and dust, which can only be removed with diiculty. l

On the floor of the bolster-case A is a perforated block, J, in which is applied the stem of a step, K, on which the spindle is sup- 8o ported. Y

Having described my invention, I claim- The combination of a bolster-case, having an oil-cup at its-upper end and a step, K, at its lower end, with a bolster which is slotted longitudinally, and providedwith a tapering longitudinally-grooved head at its upper end and a longitudinally-grooved enlargement at its lower end, substantially as described.

In testimony that I claim the foregoing as 9o my own I affix my signature in presence of two witnesses.
